To all whom it may concern:

Be it known that I, Josnr KLEIN, a'sub- 'ject of the German Emperor,residing at 44 Waldemarstrasse, Berlin, Germany, have ances for foldingand separating paper..

The general object thereof is to provide a simple and practical deviceof this char-- acter adapted to cut a paper web into pre determinedlengths and fold the lengths. to

form a block orpad.

Another object is to provide simple and practical ,means' for folding acontinuous web into sheets connected in a zig-zag manner.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction here inafter set forth, and the scopeof-the application of which will be indicated in the following claims.

Referring now to" the accompanying 6 shows the cam effecting theoperation of the; blade with its disconnecting device seen from the leftof Fig. '5; Fig. 7 is an elevation showing the'various parts inoperative relation to one another- Referring to the drawings there 'isshown a suitable frame 28yvithin which the guiding and cuttingcylind'ers2 and 3 are rotatably mounted. The latter is provided in .the usualmanner with a narrow longitudinal groove or slot adapted to receive theedge of cutting blade 6. Cylinder 2 is prov ded with a longitudinallyextending grootfie 4 and positioned therein'is thebl ade holder ornipper 5 which securely grips the cutting blade 6. The shaft7 of theblade holder is journaled indisks 8 disposed'at either end of thecylinder 2 and is, eccentrically mounted with respect to the shaftthereof, as is clearly shown in Fig. 3. A- roller 9- carried by a crankarm 10 secured upon the shaft 7 is disposed in operative relation to asprlng 11 so as to normally hold the edge of the cutting blade withinthe circumference of the cylinder 2, which position, shown in Fig. 3, itoccupies between succeeding cutting operations. Loosely mounted uponshaft 12 of cylinder 2, in a manner adapting it to be shiftedlongitudinally thereon, is a cam 13 connected as by means of the screws14 with a fork-lever 15 which prevents rotation thereof. Pivoted bymeans of the pin 18 to the machine frame, as

shown in Fig. 5, is a locking lever 16 having an elongated arm 17extending outwardly beyond the said frame, the inner end'of which isformed and adapted to engage a projection 27 of the fork-lever 15 and isI normally held in such engagement by means of aneXtensile-spring 19.The end of the arm 17 is provided with an abutment 20 which ispositioned with respect to a similar abutment 22 carried by a rotatabledisk 21 so as to be engaged thereby once during each complete revolutionof said disk, the latter rotating with a worm wheel which is itselfdriven bv a worm 23 secured to the shaft 12 of cylinder 2. The ratio ofgearing is selected to produc one revolution of the worm wheel and diskwhile the cylinder 2 performs a number of revolutiors corresponding tothe number of sheets folded into a. block or pad by means hereinafterdescribed. The

worm and worm wheel are adapted to be changed so as to produce padshaving a greater or smaller number of sheets folded therein. At eachrevolution of the dnk' 21 the tappet or abutment 22 attains the positionshown in Fig. 5 and further movement thereof carries downwardly theabutment 20 and lever arm 17, thus releasing the fork- -lever 15 andenablingthe spiral spring 24 the lever 16 to its former position. Whenthe roller 9 travels up the projection of the cam 13 the arm 10 ispressed outwardly and the blade assumes the cutting positlon shown inFig. 4. After the paper web 1 which is being drawn between the cylinders2 and-3 has been cut by the blade 6 the roller 10 passes the camprojection and is returned to its inactive position by the spring 11. Aninclined cam member carried by the terminal disk 8 now engages a roller26 pivotally mounted upon. the fork-lever 15 and presses the said leverinto its normal position, where it held by means of the locking lever16. It will be seen that the cutting blade remains in inoperativeposition until the desired number of sheets have been fed to the foldingmechanism.

Referring to Figs. 1, 2 and 7 the folding mechanism will now bedescribed. Mounted upon the frame 28 preferably in a position beneaththe cutting cylinders 2 and 3 are a pair of coacting drawing and guiderollers 29 and- 30 between which the paper web 1 passes after leavingthe cutting cylinders.

At either side of the two side pieces of the -machine frame 28, twocranks 31 and 32 are mounted to swing about the pivots 33 and, 34.Connecting members 35 are 1voted to each pair ofcranks 31 and 32 Endupon these members the folding rails 36 and 37 are fastened. Crank disks38 secured to a drive shaft 39 are united with the mem bers 35 bymeansof connecting rods 40, the crank pins 41 bein adjustably mounted inslots 42 provided in the crank disks for that purpose, thus making it asimple matter to change, at will, the length of swing of the members 31and 32. Two rock shafts 43 and 44 arejournaled in the frame 28 uponopposite sides of the table 45 and are provided with spring members 46and 47 which extend out over the edges of the table from opposite sidesand are adapted to rest upon said. table-with a suitable degree of pressure. The shafts are rocked by means of rocker arms 48 and 49 providedwith rollers 50and 51 adapted to coact with cams 52 and 53 carriedrespectively by the drawing rolls 29 and 30.

The operation of the folding mechanism is as follows: As the drive shaft39 rotates,

double cranks 31 and 32 and the rail bearing connecting members 35oscillate back and forth and cause first one and then the other of thefolding rails to pass with their inner edges close to the table, duringwhich operation they sweep by turns over the web 1 guided, as shown inFig. 1, between the said inner edges of the two rails, each rail as itpasses over the table forcing the web down in single sheets thereon,which sheets are connected to one another at their edges ina zig-zagfashion. In Fig. 1 of the drawing the opposite terminal position of thefolding rails, with their rod connections, is shown in dotted lines. Asthe member 35 moves inwardly from one extreme position the folding railwhich has lately been in contact with the paper is swung into anelevated position while the other rail moves toward the table and at thesame time passes over the corresponding springs 46 or 47 whiclr-pressdown on the sheet just folded.

52 or 53 engaging the roller 50 or 51 and causing a rocking of the shaft43 or 44. The folding rails 36 and 37 are preferably given a wedgeshaped section but may, however, consist of wires.

The drive shaft 39 receives its rotation from any suitable source ofpower and transmits same to the drawing rolls 29-30 and the cuttingcylinders 23 in any suitable manner, one arrangement being shown in Fig.7. It is to be further noted that while I have not shown such aconstruction,

if it is desired to perforate the web along the lines of the folds,suitable perforating devices may be comprised in the construction ofeither the drawing rolls or the cutting cylinders. The paper roll may bemounted in any convenient position upon or near the machine, one way ofmounting being illustrated in Fig. 7

From the foregoing it willbe seen that the present invention is one welladapted to attain, among others, all of the ends and objectshereinbefore set forth in an exceedingly simple and thoroughly practicalmanher, that the paper web will be fed to the folding mechanism at theproper rate of speed and that the same will be cut into lengths which,when folded, will give the required number of sheets to the pad.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the followingclaims is intended to cover all of-the generic and spe cific features ofthe invention herein described, and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween.

Having described my invention, whatl claim as new and desire to secureby Letters Patentis:
